COLLAR-BUTTON, 800.

SPECIFICATION formingpart of Letters Patent No. 236,402, dated January 11, 1881.

Application filed November 15, 1880.

To all whom it may concern Be it known that I, GEORGE E. ADAMS, of the city and county of Providence, in the State of Rhode Island, have invented a new and useful Improvement in Collar-Buttons, Sleeve- Buttons, and Studs; and I declare the following to be a specification thereof, reference being had to the accompanying drawings.

Figure l is an interior View of the front of the button, showin g general arrangement and connection of parts. Fig. 2 is a longitudinal section through the dotted line a: 00, Fig. 1. Fig. 3 is a longitudinal section of shoe and attached hollow post. Fig. 4 is a plan of the disk. Fig. 5 is an elevation of skeleton-post, showing slot and edge view of disk. Fig. 6 is a plan of the spring.

My invention relates to separable buttons; and it consists of a button, 850., with a slot in a skeleton-post attached to an oval disk soldered to the under side of the button-front, the skeleton-post being provided with a spring fitted into a slot cut in the post, the ends of the spring being operated by pushers passing over the disk, the ends of which enter the slot at the lower end of the post, being held against the sides of the slot by the lateral pressure of the spring, the slottedpost, together with the attached sprlng, being adapted to enter a slotted hollow post having interior beveled catches adapted to engage the ends of the pushers,

thus securing the parts of the button.

The spring 0, Figs. 2 and 6, is made of steel, German silver, or other suitable metal or metals. The metal about the head of the slot in the skeleton post may be swag-ed down upon the head of the spring, thus fastening it securely within the slot.

The slot or perforation (1, Figs. 1, 2, 4, and 5, may be made narrow at the top of the skeleton-post, so that the spring may be pressed or swaged in firmly. The sides may be straight, curved, or circular, curved or circular sides allowing the use of a longer spring, which is less apt to be strained, and is more easily operated than a-shorter one. The ends of the spring exert constantly a lateral pressure againsttheinnerends,ff, ofthe pushers, keeping them pressed against the skeleton-post G at the lower end of the slot.

To the hollow post D is attached the shoe (Modem B. In the top of this post beveled catches are cut. The hollow post is of a size and shape to receive the solid post.

The pushers are each constructed of one piece of metal, projecting through the sides a. a of the front A, maintaining a uniform width until they have passed through the lugs h h, Figs. 1, 4, and 5, when they form hooks ff, which are of the same thickness, but of much less width than the other parts of the pushers. The ends is k of the slot (1 are of a depth equal to or greater than the width of the parts of the pushers contiguous thereto, and are of sufficient width to allow of the free lateral movement of the pushers therein, but of little or no vertical motion.

The disk E, Figs. 1 and 4, is constructed of two pieces of metal. Projections are left on the upper piece, which are bent up to serve as lugs. The piece having the projections is slotted and soldered to the lower piece. The skeleton-post is soldered to the lower piece, and projects through the slot in the upper piece. The disk, as thus constructed, is soldered to the under part of the front of the button.

The parts of the button are fastened together by inclosing the skeleton-post in the hollow post, and pressing the parts together until the beveled catches of the hollow post engage with the ends of the pushers. The parts are disengaged by pressing the outer ends, b b, of the pushers between the thumb and finger, whereby the hooks are pressed closer together and the catches disengaged therefrom, allowing of the free separation of the parts.

I claim as a novel and useful invention and desire to secure by Letters Patent- 1. In a button or stud composed of two detachable parts, the front A, provided with a skeleton-post, 0, having a slot, d, with curved edges, and a spring, 0, fitted therein,the whole designed to enter a hollow post, D, with interior catches attached to the shoe B, the ends of the spring being arranged to push laterally upon pushers in the lower part of the slot, which are adapted to engage with the catches of the hollow post and be held in position by the pressure of the spring, substantially as specified.

2. In a button or stud composed of two detachable parts, the combination of a hollow post having an open-end slot with interior catches, ofa skeleton-post having a slot adapted to receive a spring therein, of a spring inserted and fastened therein, the skeleton-post and attached spring adapted to enter the hollow post, and of pushers the inner ends of which terminate in beveled hooks adapted to enter I notches or lateral extensions of the slot in the 10 skeleton-post, and designed to cooperate with the spring and. with the catches of the hollow post, whereby the parts may be locked or detached, all substantially as set forth.
